It is not the fog I hate, but the stupid people who think that because they can only see 500 yards, everyone must have their fog lights on.

Highway code Rule 211: You MUST NOT use front or rear fog lights unless visibility is seriously reduced (see Rule 201) as they dazzle other road users and can obscure your brake lights. You MUST switch them off when visibility improves.
Law RVLR regs 25 & 27

So a message for all you doppy folks who will still have you fog lights on three days from now and even though it's sunny and clear. PLEASE TURN THEM OFF. Especially the driver of the LandRover Discovery who I had to follow through slow moving traffic for 8 miles once I left the motorway.
